The Trijicon 60mm lens options are great for LD spotting. I'd say that's their purpose in life ... whether the REAP2, the Patrol 250XR or the Mk3.
I use a Mk3 60mm on a 5.56(10.3) as my night spotter ...
For long range shooting at night I pair it up with the UTC-x currently usually riding on the 7.62(22)
Shown with the PVS-14 on back only for the purpose of checking zero of the LRF (Radius) on top. It gets removed after that.

Of the ones on your list ... the Trijicon 60mm is the spotter I'd go with. Larger lens let's in more "information" and you have 4.5x optical magnification to enable long distance PID. And the image is very useful at 2x digital and still useful for 4x digital. A story on this. Once I was scanning in my alfalfa patch on 4.5x optical. I saw a black spot pretty far out there, say 300yds. It wasn't moving, so i continued my 360. After completing the 360 and seeing nothing else interesting, I came back to the black spot. I cranked up to 2x digital (9x net) magnification and thought I could make out a head. Maybe it was a Coon or a opossum? But it could've been a calf (my cattle are often in that alfalfa patch in the cool season and it was the cool season). So, I cranked up to 4x digital (18x net) and yes it gets fuzzy up there, but I could finally see movement.. The critter's mouth was moving, it was eating something. I couldn't take the risk of shooting the critter because I still did not know what it was (no PID). So I fired a shot designed to miss, call it "recon by fire" ... and the yote went from laying down eating to standing up running flat out at 40 mph in 0 nanoseconds ... unfortunately my brain was not prepared for that rapid transition and my "hail mary" follow up shot had epsilon change in hecque of connecting. I learned from that, that if you will do recon by fire, you need to be mentally prepared for what MIGHT happen.
But I tell the story to illustrate, that in that case, I could clearly see more on 4x digital than I could on 2x or 1x digital. So that 4x digital does have "some" use.
For LD shooting the only one on your list that is optimized for that is the FLIR T75 which can support 8x/12x magnification on the day scope. You can then use your day scope reticle for holding and make shots out to 500yds depending on what you are shooting at.

The image on the trijicon 60mm is good enough to shoot with out a long ways, but with no ballistic reticles you'll be using the critter as the reticle, which depending on the critter might be tough at 300yds.
The UTM is a different critter, more of a "super Patrol". But more useful at intermediate and short distances. The UTM and the Trijicon's all share the BAE OASYS cores. I'd get a skeet instead of a UTM and put the skeet on my head for hands free spotting while moving. The Skeet can DETECT out a long ways ... cows at 1800 yds ? No problem. Then you an use the Mk3 60mm to confirm PID.

So if you have to buy now, I'd get both the trijicon 60mm and the T75. Then you can use the Trijicon to spot with and the T75 to shoot with.

If you can wait maybe six months on the thermal clipon .. .Trijicon "might" be restarting the manufacturing for the UTC xii and you could buy one of those instead of the T-75. The UTC-x I have can get up to 16x easily and push up to 20x with some fuzz.
In the mean time, use the Trijicon 60mm for spotting and the PVS-30 with ELIR-3 for shooting.
